Tetris

Tetris is one of the most iconic video games ever made, originally designed by Soviet software engineer Alexey Pajitnov in 1984 while he worked at the Soviet Academy of Sciences in Moscow. The game spread rapidly across the world, became the killer app for the Game Boy in 1989, and has since sold hundreds of millions of copies across countless platforms. Decades later, play Tetris free online and discover why it remains the gold standard of puzzle games.

Tetris challenges you to arrange falling geometric pieces called tetrominoes — seven distinct shapes made of four blocks each — into complete horizontal lines on a rectangular playfield. Completed lines disappear, clearing space and earning points. If your stack of blocks reaches the top of the screen, the game is over. As your score climbs, the pieces fall faster, ramping up the pressure in a satisfying difficulty curve.

Smart Tetris play hinges on keeping your stack low and flat. Avoid leaving isolated holes that are hard to fill, and always plan two or three pieces ahead. The coveted "Tetris" move — clearing four lines at once with the long I-piece — yields the highest points. Learning to rotate pieces quickly and use wall kicks separates beginners from high-scorers. The game's rhythm is deeply satisfying, making it genuinely hard to stop.
